一、备份/etc/apt/sources.list
root@nginx-demo-deployment-59fbc48594-8gns5:/# mv /etc/apt/sources.list /etc/apt/sources.list.bak
二、写入阿里源内容
root@nginx-demo-deployment-59fbc48594-8gns5:/# echo "deb http://mirrors.aliyun.com/debian jessie main">>/etc/apt/sources.list root@nginx-demo-deployment-59fbc48594-8gns5:/# echo "deb http://mirrors.aliyun.com/debian jessie-updates main">>/etc/apt/sources.list root@nginx-demo-deployment-59fbc48594-8gns5:/#
root@nginx-demo-deployment-59fbc48594-8gns5:/# cat /etc/apt/sources.list deb http://mirrors.aliyun.com/debian jessie main deb http://mirrors.aliyun.com/debian jessie-updates main
三、清空apt缓存，执行更新
root@nginx-demo-deployment-59fbc48594-8gns5:/# apt-get clean root@nginx-demo-deployment-59fbc48594-8gns5:/# apt-get update Ign:1 http://mirrors.aliyun.com/debian jessie InRelease Get:2 http://mirrors.aliyun.com/debian jessie-updates InRelease [16.3 kB] Get:3 http://mirrors.aliyun.com/debian jessie Release [77.3 kB] Get:4 http://mirrors.aliyun.com/debian jessie Release.gpg [1652 B] Get:5 http://mirrors.aliyun.com/debian jessie/main amd64 Packages [6818 kB] Fetched 6913 kB in 3s (2017 kB/s) Reading package lists... Done root@nginx-demo-deployment-59fbc48594-8gns5:/#
速度比之前快很多
